The film, TV and Broadway star saw her career skyrocket at the age of 19 when she starred in “Singin’ in the Rain.” From there, she went on to appear in hits like “How the West Was Won” and even scored her own TV show, titled “The Debbie Reynolds Show.”

She told FOX411 when she looks back at her career, her favorite project was the one that earned her an Academy Award nomination.

“’The Unsinkable Molly Brown’ was my favorite for me to be in because it was all dancing,” she said. “There were other musicals that I made with Donald O’Connor and Gene Kelly that were wonderful pictures, and we had a lot of fun making them. They were very tough and very exhausting too because dance is very mixed—dancing is hard to photograph and hard to create.”

Reynolds said dance is her true passion. Forty years ago, she launched the Debbie Reynolds Dance Studio in Los Angeles, a business venture she is very proud of.

“I think it’s one thing to be able to dance, and it’s another thing to learn all the wonderful moments of dance because in my day… it was the moving of dance,” she said. “We didn't have any real proper school. We did not have a place to go to learn to dance and the joy of dancing.”

Her son, Todd Fisher, said Reyonds’ goal was to make dance classes inexpensive.

“One of Debbie’s goals forever has been to maintain the affordability of these classes,” he said of the classes, which cost $11. “We are one of the least expensive places to take classes, and that is because my mother did not try to make money on this but tried to make it available for everybody.”

Reynolds said the school has been a success.

“Today we have the ability to be united, and it’s most unusual for me to be able to experience the different ways you can learn the joys of dance,” she said. “That’s what I love about dance. It makes you happy, fully happy.”
